Ever been to Cobh (pron. “cove”)?
I have!
I remember when I was told how to pronounce “slainte an bhradain chugat”, which means “health of the salmon to you”, I thought my head was going to explode. IIRC, I think it’s something like “slonteh an vredoin chooth”, with the ch kind of gutteral and the th kind of sharply spirantal in that last phonetic, like the German versions of those paired consonants.
Nope, Colin is either a Welsh or a Norman name, I think. Certainly not Irish. I don’t think there is a male version of Caitlín.
The most generally accepted etymology for Colin seems to be that it’s somehow a diminutive of Nicholas.
There is an Irish name, Colm, which sounds similar to Colin (it’s a two-syllable name, believe it or not), but it’s probably not related.
That’s how it would sound if you sounded all the words out, but it normally sounds like “Blaw Clee-a”.
